go-sdk

This repository is a fork from https://github.com/ovh/go-ovh merged with https://github.com/admdwrf/ovhcli.

/!\ This project is under active development and contains a subset of OVH API GO Structures.

Lightweight Go wrapper around OVH's APIs. Handles all the hard work including credential creation and requests signing.

package main

import (
	"fmt"
	"github.com/ovhlabs/go-sdk/ovh"
)

// PartialMe holds the first name of the currently logged-in user.
// Visit https://api.ovh.com/console/#/me#GET for the full definition
type PartialMe struct {
	Firstname string `json:"firstname"`
}

// Instantiate an OVH client and get the firstname of the currently logged-in user.
// Visit https://api.ovh.com/createToken/index.cgi?GET=/me to get your credentials.
func main() {
	var me PartialMe

	client, _ := ovh.NewClient(
		"ovh-eu",
		YOUR_APPLICATION_KEY,
		YOUR_APPLICATION_SECRET,
		YOUR_CONSUMER_KEY,
	)
	client.Get("/me", &me)
	fmt.Printf("Welcome %s!\n", me.Firstname)
}

Installation

The Golang wrapper has been tested with Golang 1.5+. It may worker with older versions although it has not been tested.

To use it, just include it to your import and run go get:

import (
	...
	"github.com/ovhlabs/go-sdk/ovh"
)

Configuration

The straightforward way to use OVH's API keys is to embed them directly in the application code. While this is very convenient, it lacks of elegance and flexibility.

Alternatively it is suggested to use configuration files or environment variables so that the same code may run seamlessly in multiple environments. Production and development for instance.

This wrapper will first look for direct instanciation parameters then OVH_ENDPOINT, OVH_APPLICATION_KEY, OVH_APPLICATION_SECRET and OVH_CONSUMER_KEY environment variables. If either of these parameter is not provided, it will look for a configuration file of the form:

[default]
; general configuration: default endpoint
endpoint=ovh-eu

[ovh-eu]
; configuration specific to 'ovh-eu' endpoint
application_key=my_app_key
application_secret=my_application_secret
consumer_key=my_consumer_key

Depending on the API you want to use, you may set the endpoint to:

ovh-eu for OVH Europe API
ovh-ca for OVH North-America API
soyoustart-eu for So you Start Europe API
soyoustart-ca for So you Start North America API
kimsufi-eu for Kimsufi Europe API
kimsufi-ca for Kimsufi North America API
ovhlabs-ca for ovhlabs API
Or any arbitrary URL to use in a test for example

The client will successively attempt to locate this configuration file in

Current working directory: ./ovh.conf
Current user's home directory ~/.ovh.conf
System wide configuration /etc/ovh.conf

This lookup mechanism makes it easy to overload credentials for a specific project or user.

Register your app

OVH's API, like most modern APIs is designed to authenticate both an application and a user, without requiring the user to provide a password. Your application will be identified by its "application secret" and "application key" tokens.

Hence, to use the API, you must first register your application and then ask your user to authenticate on a specific URL. Once authenticated, you'll have a valid "consumer key" which will grant your application on specific APIs.

The user may choose the validity period of its authorization. The default period is 24h. He may also revoke an authorization at any time. Hence, your application should be prepared to receive 403 HTTP errors and prompt the user to re-authenticated.

This process is detailed in the following section. Alternatively, you may only need to build an application for a single user. In this case you may generate all credentials at once. See below.

Use the API on behalf of a user

Visit https://eu.api.ovh.com/createApp and create your app You'll get an application key and an application secret. To use the API you'll need a consumer key.

The consumer key has two types of restriction:

path: eg. only the GET method on /me
time: eg. expire in 1 day

Then, get a consumer key. Here's an example on how to generate one.

First, create a 'ovh.conf' file in the current directory with the application key and application secret. You can add the consumer key once generated. For alternate configuration method, please see the configuration section.

[ovh-eu]
application_key=my_app_key
application_secret=my_application_secret
; consumer_key=my_consumer_key

Then, you may use a program like this example to create a consumer key for the application:

package main

import (
	"fmt"

	"github.com/ovhlabs/go-sdk/ovh"
)

func main() {
	// Create a client using credentials from config files or environment variables
	client, err := ovh.NewEndpointClient("ovh-eu")
	if err != nil {
		fmt.Printf("Error: %q\n", err)
		return
	}
	ckReq := client.NewCkRequest()

	// Allow GET method on /me
	ckReq.AddRules(ovh.ReadOnly, "/me")

	// Allow GET method on /xdsl and all its sub routes
	ckReq.AddRecursiveRules(ovh.ReadOnly, "/xdsl")

	// Run the request
	response, err := ckReq.Do()
	if err != nil {
		fmt.Printf("Error: %q\n", err)
		return
	}

	// Print the validation URL and the Consumer key
	fmt.Printf("Generated consumer key: %s\n", response.ConsumerKey)
	fmt.Printf("Please visit %s to validate it\n", response.ValidationURL)
}

Use the API for a single user

Alternatively, you may generate all creadentials at once, including the consumer key. You will typically want to do this when writing automation scripts for a single projects.

If this case, you may want to directly go to https://eu.api.ovh.com/createToken/ to generate the 3 tokens at once. Make sure to save them in one of the 'ovh.conf' configuration file. Please see the configuration section.

ovh.conf should look like:

[ovh-eu]
application_key=my_app_key
application_secret=my_application_secret
consumer_key=my_consumer_key

Use the lib

These examples assume valid credentials are available in the configuration.

GET

package main

import (
	"fmt"

	"github.com/ovhlabs/go-sdk/ovh"
)

func main() {
	client, err := ovh.NewEndpointClient("ovh-eu")
	if err != nil {
		fmt.Printf("Error: %q\n", err)
		return
	}

	// Get all the xdsl services
	xdslServices := []string{}
	if err := client.Get("/xdsl/", &xdslServices); err != nil {
		fmt.Printf("Error: %q\n", err)
		return
	}

	// xdslAccess represents a xdsl access returned by the API
	type xdslAccess struct {
		Name   string `json:"accessName"`
		Status string `json:"status"`
		Pairs  int	`json:"pairsNumber"`
		// Insert the other properties here
	}

	// Get the details of each service
	for i, serviceName := range xdslServices {
		access := xdslAccess{}
		url := "/xdsl/" + serviceName

		if err := client.Get(url, &access); err != nil {
			fmt.Printf("Error: %q\n", err)
			return
		}
		fmt.Printf("#%d : %+v\n", i+1, access)
	}
}

PUT

package main

import (
	"fmt"

	"github.com/ovhlabs/go-sdk/ovh"
)

func main() {
	client, err := ovh.NewEndpointClient("ovh-eu")
	if err != nil {
		fmt.Printf("Error: %q\n", err)
		return
	}

	// Params
	type AccessPutParams struct {
		Description string `json:"description"`
	}

	// Update the description of the service
	params := &AccessPutParams{Description: "My awesome access"}
	if err := client.Put("/xdsl/xdsl-yourservice", params, nil); err != nil {
		fmt.Printf("Error: %q\n", err)
		return
	}

	fmt.Println("Description updated")
}

API Documentation

Create a client

Use ovh.NewClient() to have full controll over ther authentication
Use ovh.NewEndpointClient() to create a client for a specific API and use credentials from config files or environment
Use ovh.NewDefaultClient() to create a client unsing endpoint and credentials from config files or environment

Query

Each HTTP verb has its own Client method. Some API methods supports unauthenticated calls. For these methods, you may want to use the *UnAuth variant of the Client which will bypass request signature.

Each helper accepts a method and resType argument. method is the full URI, including the query string, and resType is a reference to an object in which the json response will be unserialized.

Additionally, Post, Put and their UnAuth variant accept a reqBody which is a reference to a json serializable object or nil.

Alternatively, you may directly use the low level CallAPI method.

Use client.Get() for GET requests
Use client.Post() for POST requests
Use client.Put() for PUT requests
Use client.Delete() for DELETE requests

Or, for unautenticated requests:

Use client.GetUnAuth() for GET requests
Use client.PostUnAuth() for POST requests
Use client.PutUnAuth() for PUT requests
Use client.DeleteUnAuth() for DELETE requests

Request consumer keys

Consumer keys may be restricted to a subset of the API. This allows to delegate the API to manage only a specific server or domain name for example. This is called "scoping" a consumer key.

Rules are simple. They combine an HTTP verb (GET, POST, PUT or DELETE) with a pattern. A pattern is a plain API method and may contain the '*' wilcard to match "anything". Just like glob on a Unix machine.

While this is simple and may be managed directly with the API as-is, this can be cumbersome to do and we recommend using the CkRequest helper. It basically manages the list of authorizations for you and the actual request.

example: Grant on all /sms and identity

client, err := ovh.NewEndpointClient("ovh-eu")
if err == nil {
    // Do something
}
req := client.NewCkRequest()
req.AddRules(ovh.ReadOnly, "/me")
req.AddRecursiveRulesRules(ovh.ReadWrite, "/sms")
pendingCk, err := req.Do()

This example will generate a request for:

GET /me
GET /sms
GET /sms/*
POST /sms
POST /sms/*
PUT /sms
PUT /sms/*
DELETE /sms
DELETE /sms/*

Which would be tedious to do by hand...

Create a CkRequest:

req := client.NewCkRequest()

Request access on a specific path and method (advanced):

// Use this method for fine-grain access control. In most case, you'll
// want to use the methods below.
req.AddRule("VERB", "PATTERN")

Request access on specific path:

// This will generate all patterns for GET PATH
req.AddRules(ovh.ReadOnly, "/PATH")

// This will generate all patterns for PATH for all HTTP verbs
req.AddRules(ovh.ReadWrite, "/PATH")

// This will generate all patterns for PATH for all HTTP verbs, except DELETE
req.AddRules(ovh.ReadWriteSafe, "/PATH")

Request access on path and all sub-path:

// This will generate all patterns for GET PATH
req.AddRecursiveRules(ovh.ReadOnly, "/PATH")

// This will generate all patterns for PATH for all HTTP verbs
req.AddRecursiveRules(ovh.ReadWrite, "/PATH")

// This will generate all patterns for PATH for all HTTP verbs, except DELETE
req.AddRecusriveRules(ovh.ReadWriteSafe, "/PATH")

Create key:

pendingCk, err := req.Do()

This will initiate the consumer key validation process and return both a consumer key and a validation URL. The consumer key is automatically added to the client which was used to create the request. It may be used as soon as the user has authenticated the request on the validation URL.

pendingCk contains 3 fields:

ValidationURL the URL the user needs to visit to activate the consumer key
ConsumerKey the new consumer key. It won't be active until validation
State the consumer key state. Always "pendingValidation" at this stage

Use SDK

Example for listing domains

package main

import (
	"fmt"
	"github.com/ovhlabs/go-sdk/ovh"
)

func main() {
	client, err := ovh.NewDefaultClient()
	if err != nil {
		fmt.Printf("Error:%s", err)
	}

	domains, err := client.DomainList()
	if err != nil {
		fmt.Printf("Error:%s", err)
	}

	for _, domain := range domains {
		fmt.Printf("Domain:%s", domain.Domain)
	}
}
